Filtering the exoplanet channel for asteroseismology uses
Tugdual Ceillier, Rafael A. García


Filtering a lightcurve can be a dangerous thing to do. Depending on what one is looking for and on what tools one is using, signal from the star can be lost in the process of filtering. In order to allow a large community - including exoplanet search, activity studies and asteroseimology - to use the data from CoRoT's exoplanet channel, we want to produce clean lightcurves without removing stellar signal. Here we will describe a way to filter the data that has been first developed for Kepler and recently applied to a sample of CoRoT lightcurves. Using the similitudes between different lightcurves, this method can get rid of global trends and other instrumental drifts and could help providing cleaner yet complete data.
